Ee 'hi l A Nnnnrr in i* s citizen oi the United States7 residing at o atagaT in the county of Knox and lil illinois, hare invented certain newand use` 'ful Improvements in Seed-Corn ihellers, ot which the followinga specification.

M invention relates to shellers and consists in a plurality oitroughened shelling elements mounted in pairs upon a longitudinal 'frameadapted to be supported upon a barrel or box and to adjust cooperatingshelling elements to and 'i irom each oth My Sheller especially.7adapted i use in shelling seed corn, ln such use it 's de` sirable toremove the defective which are present on the rounded butt and tip ofeach car and one object oit my i vention is to provide shelling elementswhich will etiiectiveljf remove such grains. y i

Anotherobject ofrny invention to vide a sheller in which different sizedti and butt ends of the ears maybe shell without readjustment oi" theshelling ela ments.

Another object oic my invention is to prcvide an arrangement of shellingelements so that not only the ends' of the ears may be shelled but alsothe intermediate portions. ln the accompanying drawings illustrat` ingmy invention- Fig. i is a plan ot my complete slieller and f F ig. 2 isa vertical transverse section take. on the line .2-2 of lig. l and shownon au enlarged scale.

rl`he frame oit the Sheller consists preterably or an angle iron havinga portion ot CII one flange cutaway intermediate its ends lo and which1s bent into lil-shape at the cutaway portion. lhe shelling elements i,2, 3, and a are mounted in pairs along the legs 5 and 6 of the frame,one pair being located near the base ot the il and the other pair beingsubstantially spaced from the pair. The base of the frame tends-tospring the two legs apart and bolt 7 provided with a nut 8 is used tolimit the movement ot' the legs from each other,

Each shelling element consists of a block having a tapered concavesurface 9 and is 7, 1921. Serial No. 42,939.

conical cups with their axis at right angles to the planekofthe frame.

By tightening or loosening nut 8 on bolt 7 the opposed shelling elementsare adjusted towards and from each other thus providing means foraccommodating unusual varia` tions in the size of the ear to beshelled.v i

Each shelling element is provided with an exterior spur l2 adapted toshell out a single row of grains which are not desired' As legs 5 and 6are flexibly united at one end oit the frame, the space between elementsyl and 2 will vitry from the space between elements 3 and 4 at all timesexcept ywhen the iframe legs are parallel. Consequently` there willalways loevtwo` sizes of shelling cups available without adjustment,onel 'for shelling the tip and the other for shelling the butt oic anear oiE corn. By spacing the outer elements sinliciently7 they may beused Vtor shelling thebody oit the ear while, at the same time, theinner shelling elementsl will be adapted for shelling the-butt or tip ofi the ear.

The free ends of the members 5 and 6 of the frame constitute handleswhereby the frame members and the shelling elements may be adjustedtoward and from each other. Y

lt will be noted that the cooperating shell-` ing elements arepositively limited in Vtheir movement from each other irrespective ofthe pressure applied by the Workman. I consider this a more advantageousarrangement than the usual construction in which by a spring or springs.

My device is exceedingly simple and economical in construction as itconsists of a length of angle iron, four simple castings or forgings andan ordinary bolt. It is adapted to be placed across a barrel or box andthe shelled grains are delivered through the separation of similarelements is restricted cov iframe to the receptacle. lt is easilyshitted 'from one receptacle to another or clamped thereon. l have shownand described a preferred embodiment of my invention, but l reserve theright to maire therein any changes or modications which Yfairly fallWithin the scope of the following claims.`

l claim:

l. ln a corn sheller, a trame comprising a pair of members flexiblyconnected at one end7 the other end of said members constituting handlesYtor moving the members toward each other. and-a plnrality oi' shellingcups spaced apart lengthwise of said iframe and each comprising a pairor shelling elements mounted on said members, the cup adjacent thedexibly connected. ends or the frame members having its shellingelements arrai'iged sn'lliciently close to receive the tip oi an ear-or'corn. and the shelling elements of the cup located adjacent the handleend of the 'trame being separated sntliciently to receive the butt of anear of corn.

il ln a corn sheller5 a iframe adapted to extend across 'the open end ofa receptacle and provided with pairs oi? adjnstably spaced shellingelements adapted to discharge shelled corn through the frame into thereceptacle, and a single adjusting means cooperating with said iframeWhereb.7 the spacing of the individual elements of each pair may bechanged and the spacing oit the elements ot one o'fA said pairs may hechanged to a greater extent than the spacing of the elements of anotherof said pairs.

3. A corn Sheller comprising anangle iron bent to form a U-shaped frame,and shelling elements mounted opposite each other on the respective legsor said frame and presenting tapered concave surfaces to each other, the

axis or said surfaces extending at right angles to the plane ot saidframe.

t. ln a corn Sheller, longitudinal frame members iexibly connected atone end, a

, pair or cooperating shelling elements mount ed opposite each other onsaid members, and a secondL pair of cooperative shelling elementsmounted opposite each other on said members at a point spaced from saidfirst mentioned elements.

L corn sheller comprising an angle iron having one. flange cnt awayintermediate the ends ot the angle yiron and the other ange `bent etthis point to form a U-shaped frame, and shelling elements mountedopposite each other on said lrame and presenting tapered,

concave, ronghened surfaces towards each' other.

'6. :i corn sheller comprising an angle iron bent into a llJ-shape,pairs ofshelling elements spaced alone the straight portions ot theangle With 'the elements of each pair presenting roughened concavesurfaces towards each other, and a. member extending transversely of thestraight portions o the angle and limi ting the movement of saidelements away from each other.

7. A corn Sheller comprising a pair ot substantially parallel Jframemembers con A ne Led together at one end and spaced apart at the otherend, a pair of shellers each comprising a air or' co-operating shellingelements mounted upon said frame members, one oil said shellers beinglocated adjacent the connected end of said frame members, and the otherorf said shellers being located between said iirst mentioned sheller andthe free end o; said frame members.
